This invention relates to improvements-in fire potsfor lfuel burners, and has for its object to provide 'a device of that character comprising a main shell formed of steel, or the like, and supplemented by a refractory lining so located as to receive the maximum heat to prevent deterioration of the shell. l

This and other objects will be more fully described in the following specification and shown in the accompanying drawing, in which- Fig. 1 is ya plan view 4of, my improved construction,

Fig. 2 is a lvertical section taken along the line 2-2'of Fig. 1. l

10 indicates general] the shell of a lire pot, generally of circu ar form, having the side wall 10a inclined 'from bottom to top, and with inlet openings 10b and 10 at one side, also the passages 10d and 10.e at either side of the ports 10b and 10". `These ports and passages are provided to permit injecthe fuel, air, pilot light, or the like. At its upper portion the side wall 10 is offset to provide the horizontal shoulderlOt and the vertical wall portion v 10g. Detachably mounted upon the shoulder 10r is the refractory ring orcollar 611 constructed of suitable refractory materlal, and havin its inner periphery inclined inwardly from ottom to top as indicated by numeral 11, to generally continue `the surface. of the lower portion of the iire ot chamber. i

In practice the fuel is lnjected or other- 'wise supilied to the fire pot chamber and circulate thereabout durin or after combustion. The tenden 'of t e burnln fuel or fuel mixture is to rise, and the maximum heat zone is at the upper portion, so that the deterioration eifect thereofpis `received by the refractory Y I terioration of the surrounding metal shell,

and to an a transmitted!) t v the appended claims; v

ring 11, which thus prevents de..

reciable extent reducesthe heat4 erethrou h. At the same time this refractory ring w en heated'is not so equalize the' heat adjacent the zone of atomization 'and combustion.

When necessary the refractoryring maya` be readily replaced -with little expense and 5o no inconvenience.

It will be" obviousvthat m invention is susceptible of modification an improvement, and I do not wish to be restricted to the form shown and described, ex'vcept as defined in 55 f What I claini is: p

1. A fire pot for fuel burners comprising a metal fire pot shell having an open to portion, and a ring of refractor materi the inner end of the bore of whic re isters withV the `bore of Isaid open top, sai `'rin being supported wholl above the pot an positioned approximate y in the zone of most intense heat normally' developed by the burner in operation, the bore of said'ring beingof approximatel the same diameter as the interior of the s ell and the surface of said bore forming an approximate continuation of the inner surface of saidshell. 70

2. A lire pot for fuel burners comprising a metal fire pot shell having an o nftop, portion, said shell having outward y'oifset portions contiguous to the open topportion, and a ring of refractory nihaterialv a bottom face restin upon said offset portlons' and its borea't e inner end thereof in 'register with said top enii1g,sid bore befx ing of, approximatel e same diameter as. the vinterior ofthe A ell and the surface of S lthe bore forming an approximate continua- '.ti'on of the inner surface of said shell, said.

ring being whollysupported'abovel the pot an positioned approximatey most intense heatnormall'y e burner in operation.`

'In witness whereofz I hereunto subscribe my name to this specification. e
